Current research at Huertas laboratory aims to understand olfaction in vertebrates using fish as a model. Fish have a highly sensitive sense of the smell which is involved in the control of critical physiological functions as reproduction, feeding, navigation, prey detection and alarm responses. Our different lines of research include basic research projects that seek to understand the olfactory process in vertebrates and applied research projects that target aquaculture practices and environmental management. To achieve our goals, we use several techniques that we have refined, including electrophysiology, steroid quantification, protein biochemistry (to investigate the morphology and physiology of elements of the hypothalamus-pituitary-gland axis), histology and molecular procedures. Our goal is to advance the understanding of the vertebrate olfactory process and provide new tools for managing of fish populations. The current lines of research in the laboratory include:
• Olfactory immune function
• Effects of nitrite in olfaction
• Effects of nanoplastic in olfaction
• Fish chemical communication
